Blue laser module technology from SLD Laser debuts
The blue laser technology works with copper, aluminum, and stainless steel, as well as other metals such as nickel, gold, titanium, and silver.
SLD Laser's high-power, high-brightness blue laser module technology reportedly features up to 12X the absorption, processing quality, and speed compared to infrared (IR) laser technology. The blue laser technology works with copper, aluminum, and stainless steel, as well as other metals such as nickel, gold, titanium, and silver that are commonly used for plating, other thin metal processes, and 3D printing. Its light output is also highly absorptive in nonmetals and organics, enabling its use in marking, engraving, and cutting of these materials. For biomedical applications, the technology is said to exhibit more than 10X absorption in blood hemoglobin and melanin in skin than IR lasers, enabling next-generation solutions in dermatology and surgery.
The technology has a form factor roughly the size of a credit card, and delivers over 20 W from a 100 µm transport fiber. It is modular and can be power-scaled and aggregated with optical fibers into higher power systems to deliver hundreds of watts from high-brightness delivery fibers <600 µm in diameter.
